All Lady Bricks jewellery follows UK hallmarking guidelines. Hallmarks are a fascinating insight into a piece of jewellery, telling you about the fineness of the precious metal, the maker, and more. They're also a legal requirement in the UK for precious metals over a particular weight limit — for sterling silver, any item of jewellery with more than 7.78g of sterling silver in it must be hallmarked. 

​

If your item of jewellery is above that weight limit, it will feature a full UK traditional hallmark from the London Assay Office, helping make it a piece of heirloom jewellery you can treasure for a lifetime and beyond.
